Application med June 7, ieee. serial No. intesi.

yMy present invention has reference to a whistle which may be employedas a warning signal on automobiles,.an alarm, or as amusical instrument.Y

In carrying'o-ut my invention it is my purpose to produce a whistle thatis operated by a fluid under pressure, such for instance, as the exhaustgases from an internal com* bustion engine, and in which' the deviceincludesa lpipe or cylinder having its/mouth coupled with the engineexhaust, and the passage of gasthereinto controlled by a valveoperatedin a Vvnovel manner from a convenient point in the automobildandalso in which a springginfluenced vplunger is arranged in the `pipe orcylinder andmovable to differentpositions-therein by means varranged inclose proximityto the valveA op-A erating means, the movement oftheplunger serving to increase the volume of .sound at the pleasure of theoperator, and as the lsound therebybecomes deeperthev same may be tunedto a variety of notes.

To the attainment of the above broadly stated objects and many otherswhich will present themselves as the naturewof the invention is betterunderstood the improvement resides in certain novel features ofconstruction, combination and operative `association of parts,a'satisfactory embodiment Vof which is disclosed bythe accompanyingdrawings.

' therethrough.

The vface of the vplunger confronting the block 4 is dished, as at 19,and the closed end 16 of the cylinder has spaced apertures Connected toan eye on the outer end of therod 17 there is a rod or flexible element20.

On the dash board or on the Wfloor board at the front of the automobileto which the whistle is attached there is a plate 21, which ispreferably round in plan. The plate has a central cross member 22provided. with a lateral extension 23 that has its outer end disposed atan angle, widened and bifurcated to provide spaced arms 24. Fassingthrough a threaded opening in the outer arm there is a threaded bindingelement 25. The arm is preferably provided with a compressihle facing,and these arms 24 are'designed to receive therebetween the instrumentboard desired plate in the 26 kof the automobile. As previously intifmated, the plate 21 may be secured at any automobile.

lThe upper edge of the rounded plate 21 is provided with spaced notches27, and any one of these notches is designed to be engaged by a springinfluenced dog 28 on lower face of a lever v29. The lever is pivoted, asat 30, to the under face ofthe supporting plate 21. The lever ispreferably integrally formed with upstanding lugs 31, and betweenYthesel lugs there is pivoted, as

at 32, the bent or offset portion of ,a second Y lever 33 which isdisposed directly over the lever 29. The pivot 32 passes through one dof aplurality of openings in the lever 33,

and the end of the lever, adjacent to its said pivot 32, has Ysecuredthereon an angle bracket 34. As a matter-of-fact, the outer end of thelever 33 may be bifurcated instead of being provided with the removablysecured bracket, and the bifurcated end of the said lever has elongatedslots 35 therethrough. These slots are designed to receive therethroughlaterally extending lugs 36 on the reduced end 37 of an arm 38. The

arm is pivotally supportedvbetween the upstanding lugs 40 on the crossvbar 22 of the supporting plate 21.v The outer end of the arinfisconnected to the element 14. Y

Loosely connected to the lever 33 there is ya link 41.V This link has anodset end which is pivotally secured to an angle or upstanding flange 42on the offset end of a plate 43. The plate is pivoted, as at 44, to alug 45 on the cross bar 22. The plate 43 has passed Y therethrough theShanks of a pair of bolt members r4t, the said shanks also passingthrough one pair of equidistantly spaced apertures 47 on a second plate48. Nuts 49 are screwed on the bolts 46, andthe outer plate 48 isconnected to the element 2O.V

The spring influenced crank lever 10 for the valve plate 7 willinitiallydraw on the element 14 to swing or cant the arm or plate 38, and therebyswing the outer end of the the Y ing the saine to draw on the element 14to operate the crank shaft and raise the valve plate toy what may betermed open position, or to bring its opening 9 into register with theopening 5 inthe block 4, so thatthe exhaust gases iliiaseingl iito themouth of the i cylinder willY create a sound in the well known manner.il ow by swinging the lever 29 together with the lever v33, pull will beexerted upon the .element 2O to arrange the plunger 19 in desired.positions in the cylinder This movement ofthe plunger permits the gasesflowing to determined extents into the cylinder 3 and being resisted bycontact with the plunger will from thence be redirected and find anoutlet through the orifice 6 so that compound notes will be produced andsounded. It will be apparent that with little practice a person can somanipulate the levers as to cause the instrument toplay various tunes.

It is believed that the foregoing description when read' in' connectionwith the accompanying` drawings will fully set forth the simplicity andadvantages of my improvement to those skilled in the Vart to which'suchinventions relate, but it is, of course, to be understood that l do notwish to be restricted to the precise details of construction herein setforthv and hold myself entitled to make all such changes therefrom asfairly fall within the scope of what l claim, providing, of course, thatsuoli Vchanges do not depart from the spirit or sacrifice any of theadvantages of the invention.

Having claim Y 1. A whistle, including a cylinder designed to have itsmouth attached to the exhaust pipe of an internal combustion en-Y gine,said cylinder having a block partly closing the mouth thereof and havingan described the invention,

2. A whistle, including a' cylinder, having a throat end designed. tobeattached to a conductor for fluid which is under pressure, saidcylinder having a block on the said throat thereof, partly closing thesame,

aspring influenced plunger inthe cylinder,l lieXlble elements connectedto the crank shaft and to the plunger, ra round support plate havin@ oneof its edges notched, a forked bracket on the support, having a bindingelement associated therewith, a lever pivotally secured to the supportplate, a spring influenced plunger thereon for engaging in the notchesof the said support r plate, a second lever disposed above and pivotallylassociated with the first mentioned lever, an arm pivotally secured onthe support plate, loosely ,connectedv With the last mentioned leverandl having its outer end connected With the flexible velement-of thecrank shaft, a link loosely connected to the last mentioned lever, aplate pivotally'secured on the support-l plate hav# ing an olfset endlvtol which the link is loosely connected, a second plate adjustahlysecured on the lirst mentioned plate and said second plate beingconnected to the flexible element for kthe plunger. f

In testimony whereof I affix my signature.
